What are the guidelines for the What are the guidelines for the analysis of factors that affect rainfall?
Rainfall is an essential climatic factor that determines the distribution of water on the Earth's surface, directly affecting living environments, ecosystems, and human economic activities. Rainfall is not evenly distributed across areas and affected by numerous factors such as air pressure, fronts, wind, ocean currents, and terrain.
Students may refer to the following guidelines for the analysis of factors that affect rainfall:
| 1. Air Pressure - Low Pressure Area: This is where air is drawn upwards, cooled, condensed, forming clouds, leading to rain. Low pressure areas generally have high rainfall, typical of the equatorial region. - High Pressure Area: Here, air is compressed, unable to ascend to form clouds, resulting in little or no rain. Areas such as the polar regions and the tropics are examples of this phenomenon. 2. Fronts - A front is the boundary between two masses of air with different temperatures and characteristics. When warm air rises over cold air at fronts, intense moisture condensation occurs, causing rain. - Regions with warm fronts, cold fronts, or tropical convergence zones often have frequent heavy rains. For example, the tropical convergence area in the East Sea usually experiences prolonged heavy rain. 3. Wind - Ocean Wind: Coastal areas or regions receiving winds from the ocean usually have high rainfall due to evaporation from the sea. - Inland Areas: Regions without moisture-bearing winds from the sea are usually less rainy, sometimes even deserts. - Monsoon: Areas with active monsoons (such as Southeast Asia) usually have heavy rains during the moist monsoon from the ocean. - Trade Winds: Areas with strong trade winds are often arid with little rainfall. 4. Ocean Currents - Warm Ocean Currents: When warm currents flow along the coast, the increased temperature causes more evaporation, leading to heavy rain. For example, coastal areas affected by the Gulf Stream in the Atlantic. - Cold Ocean Currents: In coastal regions with cold currents, moisture condenses before reaching the shore, leading to aridity. For example, the Atacama Desert on the Pacific coast, affected by the Humboldt Current. 5. Terrain - Elevation: In areas with high terrain, air moving upwards cools, causing moisture to condense, leading to rain. However, beyond a certain height, the air becomes dry and rainless. - Windward and Leeward Slope: + Windward Slope (main wind direction carrying moisture): High rainfall due to moist air rising, cooling, and condensing. + Leeward Slope: Less rain or dry conditions as the air loses most moisture after crossing the windward slope. 6. Conclusion Rainfall in an area results from a combined effect of natural factors such as air pressure, fronts, wind, ocean currents, and terrain. These factors don't operate independently but often coordinate, causing uneven distribution of rainfall on the Earth's surface. Understanding these factors not only helps explain climatic phenomena but also aids in water resource management and effective weather forecasting. |

What learning outcomes are required for 10th-grade students in Vietnam regarding the atmospheric content in the Geography curriculum?
According to Section 5 of the General education program in Geography issued along with Circular 32/2018/TT-BGDDT, the learning outcomes required for 10th-grade students in Vietnam regarding the atmospheric content in the Geography curriculum are as follows:
- Define the concept of atmosphere.
- Present the distribution of air temperature on Earth by geographic latitude; continents, oceans; terrain.
- Present the formation of air pressure belts on Earth, reasons for changes in air pressure.
- Present several main wind types on Earth; some local wind types.
- Analyze factors affecting rainfall and present its global distribution.
- Analyze data tables, diagrams, maps, and sketches of several atmospheric elements (temperature, air pressure, wind, rain).
- Read climate zone maps on Earth; analyze some climate diagrams.
- Explain some weather and climate phenomena in reality.
